I'm unable to enable passkeys in kratos (self-hosted). I updated my kratos.yml and identity-schema.json based on this page (https://www.ory.sh/docs/kratos/passwordless/passkeys#passkeys-with-the-dedicated-passkey-strategy), but upon starting kratos, I get the error:

The configuration contains values or keys which are invalid: ... additionalProperties "passkey" not allowed
